Intensive support does not improve positive-airway pressure use in spinal cord injury/disease: a randomized clinical trial.

STUDY OBJECTIVE: Treatment of sleep-disordered breathing (SDB) with positive airway pressure (PAP) therapy has unique clinical challenges in individuals living with spinal cord injuries and diseases (spinal cord injury [SCI]/D). Interventions focused on increasing PAP use have not been studied in this population. We aimed to evaluate the benefits of a program to increase PAP use among Veterans with SCI/D and SDB. METHODS: Randomized controlled trial comparing a behavioral Intervention (n = 32) and educational control (n = 31), both including one face-to-face and five telephone sessions over 3 months. The intervention included education about SDB and PAP, goal setting, troubleshooting, and motivational enhancement. The control arm included non-directive sleep education only. RESULTS: Primary outcomes were objective PAP use (nights ≥4 hours used within 90 days) and sleep quality (Pittsburgh Sleep Quality Index [PSQI] at 3 months). These did not differ between intervention and control (main outcome timepoint; mean difference 3.5 [-9.0, 15.9] nights/week for PAP use; p = .578; -1.1 [-2.8, 0.6] points for PSQI; p = .219). Secondary outcomes included fatigue, depression, function, and quality of life. Only fatigue improved significantly more in the intervention versus the control group (p = .025). Across groups, more PAP use was associated with larger improvements in sleep quality, insomnia, sleepiness, fatigue, and depression at some time points. CONCLUSIONS: PAP use in Veterans with SCI/D and SDB is low, and a 3-month supportive/behavioral program did not show significant benefit compared to education alone. Overall, more PAP use was associated with improved symptoms suggesting more intensive support, such as in-home assistance, may be required to increase PAP use in these patients.

Feasibility of oropharyngeal and respiratory muscle training in individuals with OSA and spinal cord injury or disease: A pilot study.

OBJECTIVES: To examine the feasibility of individuals with spinal cord injury or disease (SCI/D) to perform combined oropharyngeal and respiratory muscle training (RMT) and determine its impact on their respiratory function. METHODS: A prospective study at a single Veterans Affairs (VA) Medical Center. Inclusion criteria included: 1) Veterans with chronic SCI/D (>6 months postinjury and American Spinal Injury Association (ASIA) classification A-D) and 2) evidence of OSA by apnea-hypopnea index (AHI ≥5 events/h). Eligible participants were randomly assigned to either an experimental (exercise) group that involved performing daily inspiratory, expiratory (using POWERbreathe and Expiratory Muscle Strength Trainer 150 devices, respectively), and tongue strengthening exercises or a control (sham) group that involved using a sham device, for a 3-month period. Spirometry, maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP), polysomnography, and sleep questionnaires were assessed at baseline and at 3 months. RESULTS: Twenty-four individuals were randomized (12 participants in each arm). A total of eight (67%) participants completed the exercise arm, and ten (83%) participants completed the sham arm. MIP was significantly increased (p < 0.05) in the exercise group compared with the baseline. CONCLUSIONS: Combined oropharyngeal and RMT are feasible for individuals with SCI/D. Future studies are needed to determine the clinical efficacy of these respiratory muscle exercises.

Veterans' Experiences of Support in Managing Comorbid Sleep Apnea and Type 2 Diabetes.

BACKGROUND: Obstructive sleep apnea (OSA) is highly prevalent in patients with Type 2 diabetes, more so in veterans compared with nonveterans. Positive airway pressure is the recommended first-line treatment for OSA. However, adherence to both positive airway pressure and diabetes management regimens can be challenging for older adults. Support from family or friends may improve glucose control or sleep-apnea-related symptoms, yet the evidence is limited when both conditions coexist. OBJECTIVES: This study aimed to describe veterans' experiences of support from family and friends with managing comorbid sleep apnea and Type 2 diabetes. METHODS: We conducted a postal survey of older veterans with OSA and Type 2 diabetes from one healthcare system. Questions include demographic and health-related information, information about sleep apnea and diabetes treatment and education received, related support from family or a friend, perceived benefits of regular positive airway pressure device use on improving sleep health, and perceived benefits of education for family or a friend on sleep apnea and diabetes. Descriptive and bivariate analyses were performed. RESULTS: Of 145 respondents (mean age = 72 years), 43% reported receiving help for Type 2 diabetes from family or a friend. Almost two thirds of the respondents were currently using a positive airway pressure device, of whom 27% received support with device use from family or friends. About one third of veterans perceived family and friends receiving education on treating sleep apnea and diabetes to be very or extremely helpful. Such perceived benefit was higher among those who were married or identified as non-White. Veterans using a positive airway pressure device had lower hemoglobin A1c levels than nonusers. DISCUSSION: Veterans perceived that additional education for the individuals providing support would be beneficial. Future studies could address interventions to increase sleep apnea and Type 2 diabetes knowledge among families and friends of veterans with these comorbid conditions. In addition, patients' adherence to positive airway pressure may be enhanced by support from family and friends.

Identifying gaps in clinical evaluation and treatment of sleep-disordered breathing in women veterans.

PURPOSE: Sleep-disordered breathing (SDB) is a common sleep disorder in veterans; however, limited research exists in women veterans. We sought to estimate patterns of care in terms of evaluation, diagnosis, and treatment among women veterans with factors associated with elevated SDB risk. METHODS: Within one VA healthcare system, women identified through electronic health record data as having one or more factors (e.g., age >50 years, hypertension) associated with SDB, completed telephone screening in preparation for an SDB treatment study and answered questions about prior care related to SDB diagnosis and treatment. RESULTS: Of 319 women, 111 (35%) reported having completed a diagnostic sleep study in the past, of whom 48 (43%) were diagnosed with SDB. Women who completed a diagnostic study were more likely to have hypertension or obesity. Those who were diagnosed with SDB based on the sleep study were more likely to have hypertension, diabetes, or be ≥50 years old. Of the 40 women who received treatment, 37 (93%) received positive airway pressure therapy. Only 9 (24%) had used positive airway pressure therapy in the prior week. Few women received other treatments such as oral appliances or surgery. CONCLUSIONS: Findings support the need for increased attention to identification and management of SDB in women veterans, especially those with conditions associated with elevated SDB risk.

Pilot RCT Testing A Mailing About Sleeping Pills and Cognitive Behavioral Therapy for Insomnia: Impact on Benzodiazepines and Z-Drugs.

OBJECTIVES: The aim is to pilot a low-touch program for reducing benzodiazepine receptor agonist (BZRA; benzodiazepines, z-drugs) prescriptions among older veterans. METHODS: Pilot randomized controlled trial consists of 2,009 veterans aged ≥ 65 years who received BZRA prescriptions from a Veterans Health Administration pharmacy (Colorado or Montana) during the prior 18 months. Active: Arm 1 was a mailed brochure about BZRA risks that also included information about a free, online cognitive behavioral therapy for the insomnia (CBTI) program. Arm 2 was a mailed brochure (same as arm 1) and telephone reinforcement call. Control: Arm 3 was a mailed brochure without insomnia treatment information. Active BZRA prescriptions at follow-up (6 and 12 months) were measured. RESULTS: In logistic regression analyses, the odds of BZRA prescription at 6- and 12-month follow-ups were not significantly different for arm 1 or 2 (active) versus arm 3 (control), including models adjusted for demographics and prescription characteristics (p-values >0.36). CONCLUSIONS: Although we observed no differences in active BZRA prescriptions, this pilot study provides guidance for conducting a future study, indicating a need for a more potent intervention. A full-scale trial testing an optimized program would provide conclusive results. CLINICAL IMPLICATIONS: Mailing information about BZRA risks and CBTI did not affect BZRA prescriptions.

A Scoping Review and Conceptual Framework Examining the Role of Sleep Disturbance in Financial Exploitation in Older Adults.

Sleep disturbances and financial exploitation have both been linked to impaired cognitive ability, loneliness, and depressed mood in older adults, suggesting a potential role of sleep disturbances in increasing vulnerability to financial exploitation. We sought to identify evidence linking sleep disturbances to financial exploitation. We conducted a systematic search of MEDLINE, PubMed Central, and National Center for Biotechnology Information Bookshelf for relevant published articles on sleep and financial exploitation. Three studies examining both sleep and financial exploitation were identified. None of the studies explored sleep disturbances as a cause of financial exploitation. More work needs to be done to examine the role of sleep disturbances in financial exploitation. We propose a conceptual framework for identifying possible associations among sleep disturbance, biopsychosocial, and decision-related situational factors to guide further exploration of relationships between sleep and financial exploitation.

Declining trend in use of medications for sleep disturbance in the United States from 2013 to 2018.

STUDY OBJECTIVES: Recent initiatives to discourage overprescription of sleep medications have increased awareness of their potential adverse effects; however, it is unknown whether these efforts translated into a decline in use of these medications in the United States. We assessed recent national trends in the use of medications used for sleep disturbance. METHODS: We used data from n = 29,400 participants in the 2013-2018 National Health and Nutrition Examination Survey. At each of three waves of in-person assessments, participants presented prescription bottles for all medications used in the prior month. Interviewers recorded each medication and participants self-reported duration and reasons for use. We identified all medications used for sleep disturbance and categorized medications into two categories: Food and Drug Administration-approved sleep medications and those used off-label for sleep disturbance. We examined changes in the prevalence in use of these medications across the study period. RESULTS: The odds of using medications for sleep disturbance decreased 31% between 2013 and 2018 (odds ratio = 0.69, 95% confidence interval = 0.51-0.93, P = .015). This trend was driven by declines in use of Food and Drug Administration-approved medications for sleep disturbance, especially for medium- and long-term duration of use. Notably, among those age 80+ years, we observed an 86% decline (odds ratio = 0.14, 95% confidence interval = 0.05-0.36, P < .001) in use of Food and Drug Administration-approved sleep medications over the study period. CONCLUSIONS: Use of prescription medications for sleep disturbance declined nationally, suggesting a possible effect of efforts to curb overprescription and encourage judicious use of these agents. Future research needs to examine whether these changes have coincided with improved population sleep health. CITATION: Kaufmann CN, Spira AP, Wickwire EM, et al.

Considerations for integrated cognitive behavioural treatment for older adults with coexisting nocturia and insomnia.

Nocturia and chronic insomnia disorder are common conditions that frequently coexist in older adults. Existing medication treatments for each condition have risks, particularly in older adults. While treatment guidelines recommend starting with behavioural therapy for each condition, no existing program simultaneously addresses nocturia and insomnia. Existing behavioural interventions for nocturia or insomnia contain concordant and discordant components. An expert panel (including geriatricians with sleep or nocturia research expertise, sleep psychologists and a behavioural psychologist) was convened to combine and reconcile elements of behavioural treatment for each condition. Concordant treatment recommendations involve using situational self-management strategies such as urge suppression or techniques to influence homeostatic drive for sleep. Fluid modification such as avoiding alcohol and evening caffeine and regular self-monitoring through a daily diary is also appropriate for both conditions. The expert panel resolved discordant recommendations by eliminating overnight completion of voiding diaries (which can interfere with sleep) and discouraging routine overnight voiding (a stimulus control strategy). The final product is an integrated cognitive behavioural treatment that is delivered by advanced practice providers weekly over 5 weeks. This integrated program addresses the common scenario of coexisting nocturia and chronic insomnia disorder.

Change in Dysfunctional Sleep-Related Beliefs is Associated with Changes in Sleep and Other Health Outcomes Among Older Veterans With Insomnia: Findings From a Randomized Controlled Trial.

BACKGROUND: Cognitive behavioral therapy for insomnia (CBTI) targets changing dysfunctional sleep-related beliefs. The impact of these changes on daytime functioning in older adults is unknown. PURPOSE: We examined whether changes in sleep-related beliefs from pre- to post-CBTI predicted changes in sleep and other outcomes in older adults. METHOD: Data included 144 older veterans with insomnia from a randomized controlled trial testing CBTI. Sleep-related beliefs were assessed with the Dysfunctional Beliefs and Attitudes about Sleep-16 (DBAS-16, subscales: Consequences, Worry/Helplessness, Sleep Expectations, Medication). Outcomes included sleep diary variables, actigraphy-measured sleep efficiency, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Flinders Fatigue Scale (FFS), Patient Health Questionnaire-9, and health-related quality of life. Analyses compared slope of change in DBAS subscales from baseline to posttreatment between CBTI and control, and assessed the relationship between DBAS change and the slope of change in outcomes from baseline to 6 months. RESULTS: Compared to controls, the CBTI group demonstrated stronger associations between improvement in DBAS-Consequences and subsequent improvement in PSQI, ISI, ESS, and FFS. The CBTI group also demonstrated stronger associations between improvement in DBAS-Worry/Helplessness and subsequent improvements in PSQI, ISI, and FFS; improvements in DBAS-Medication and PSQI; and improvements in DBAS-Sleep Expectations and wake after sleep onset (sleep diary) and FFS (all p < .05). CONCLUSIONS: Significant reduction in dysfunctional sleep-related beliefs following CBTI in older adults predicted improvement in several outcomes of sleep and daytime functioning. This suggests the importance of addressing sleep-related beliefs for sustained improvement with CBTI in older veterans. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00781963.

Posttraumatic Stress Disorder Risk and Benzodiazepine Dependence in Older Veterans with Insomnia Symptoms.

OBJECTIVES: To measure the rate of benzodiazepine receptor agonist (BZA) dependence in older veterans with insomnia symptoms chronically using BZAs and to assess for associations between high posttraumatic stress disorder (PTSD) risk and BZA dependence. METHODS: A cross-sectional study was conducted among veterans aged 55 years and older with insomnia symptoms (current or historical) and chronic use of BZAs (≥3 months). Measurements included the Primary Care-PTSD screen (score >2 indicates high PTSD risk) and Benzodiazepine Dependence Questionnaire. Logistic regression was used to test for associations between PTSD risk and BZA dependence. RESULTS: A high PTSD risk was observed in 40% of the participants (N = 33). One-fifth (21.7%, N = 18) of participants met the criteria for benzodiazepine dependence (score ≥23 on Benzodiazepine Dependence Questionnaire). Veterans with high PTSD risk were significantly more likely to have BZA dependence (odds ratio 10.09, 95% CI [2.39, 42.54], p = .002). CONCLUSIONS: In older veterans with insomnia symptoms and chronic use of BZAs, high PTSD risk is associated with elevated risk for BZA dependence, which may make discontinuation of these medications difficult. CLINICAL IMPLICATIONS: Clinicians should consider the strong association between PTSD symptoms and benzodiazepine dependence when developing plans to taper a BZA in veterans with these symptoms.

Care coordination needs for deprescribing benzodiazepines and benzodiazepine receptor agonists.

Deprescribing of medications such as benzodiazepines and benzodiazepine receptor agonists (z-drugs) can be a complex process that varies across practices, specialties, and health care systems. Care coordination among healthcare providers, patients, families, and other healthcare system components is critical to achieving high levels of deprescribing and person-centered care. We present a framework for promoting care coordination in the context of benzodiazepine/z-drug deprescribing. Future efforts are needed to study the impact of better care coordination on benzodiazepines/z-drug discontinuation and other outcomes that are important to stakeholders.

Benefits of Cognitive Behavioral Therapy for Insomnia for Women Veterans with and without Probable Post-Traumatic Stress Disorder.

OBJECTIVE: This study compared the benefits of cognitive-behavioral therapy for insomnia for sleep, mental health symptoms, and quality of life (QoL) in a sample of women veterans with and without probable post-traumatic stress disorder (PTSD) comorbid with insomnia disorder. METHODS: Seventy-three women veterans (30 with probable PTSD) received a manual-based 5-week cognitive-behavioral therapy for insomnia treatment as part of a behavioral sleep intervention study. Measures were completed at baseline, post-treatment, and 3-month follow-up. Sleep measures included the Insomnia Severity Index, Pittsburgh Sleep Quality Index, sleep efficiency measured by actigraphy, and sleep efficiency and total sleep time measured by sleep diary. Mental health measures included the PTSD Checklist-5, nightmares per week, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7 scale. QoL was measured with the Short Form-12. Linear mixed models compared changes over time across groups. Independent t tests examined PTSD symptom changes in women veterans with probable PTSD. RESULTS: Both groups demonstrated improvements across sleep (ps < .001-.040), mental health symptoms (ps < .001), and QoL measures (ps < .001). The probable PTSD group reported greater improvements in diary sleep efficiency (p = .046) and nightmares per week (p = .001) at post-treatment and in total sleep time (p = .029) and nightmares per week (p = .006) at follow-up. Most participants with probable PTSD experienced clinically significant reductions in PTSD symptoms at post-treatment (66.7%) and follow-up (60.0%). Significant reductions in intrusive and arousal/reactivity symptoms were maintained at follow-up. CONCLUSIONS: Cognitive-behavioral therapy for insomnia improves insomnia, mental health symptoms, and QoL among women veterans, with greater improvement in those with probable PTSD.

Sleep Disruption Due to Stress in Women Veterans: A Comparison between Caregivers and Noncaregivers.

Objective/Background: Sleep problems are common in women and caregiving for an adult is a common role among women. However, the effects of caregiving on sleep and related daytime impairment are poorly understood among women veterans. This study compared stress-related sleep disturbances, insomnia symptoms, and sleep-related daytime impairment between women veterans who were caregivers and those who did not have a caregiving role. Participants: Of 12,225 women veterans who received care in one Veterans Administration Healthcare System, 1,457 completed data on a postal survey (mean age = 51.7 ± 15.9 years). Two hundred forty three (17%) respondents (mean age 53.8 ± 12.7 years) were caregivers for an adult, predominantly for a parent, providing transportation. Methods: The survey included items that addressed insomnia symptoms, total sleep time, sleep-related daytime impairments, caregiving characteristics, self-rated health, pain, stress, body mass index, and demographic information. Results: In adjusted analyses, caregiver status did not directly predict sleep complaints alone. However, in multiple regression analyses, being a caregiver (odds ratio 1.7, p = .001) significantly predicted stress-related sleep disturbance, even after adjusting for age, pain, self-rated health, and other characteristics. Furthermore, being a caregiver (ß = 3.9, p = .031) significantly predicted more symptoms of sleep-related daytime impairment after adjusting for age, pain, self-rated health, and other factors. Conclusions: Compared to noncaregivers, women veterans who were caregivers for an adult were more likely to report stress causing poor sleep, and more daytime impairment due to poor sleep. These findings suggest the need to target stress and other factors when addressing sleep disturbance among women veterans who are caregivers.

Development of a dyadic sleep intervention for Alzheimer's disease patients and their caregivers.

PURPOSE: This study aimed to refine a behavioral sleep intervention program targeting patients with Alzheimer's disease and their caregivers. METHODS: In this case series, key components of the sleep program were built upon previous intervention studies of patients with cognitive impairment/dementia. The intervention consisted of five weekly sessions covering sleep hygiene, sleep compression, stimulus control, daily walking/light exposure, relaxation/mindfulness, and caregiver training to manage patients' behavioral problems. The materials and structure were iteratively refined based on feedback from caregivers and sleep educators. Sleep diaries were used to evaluate sleep outcomes. RESULTS: Five out of six enrolled dyads completed the sessions. Several revisions were made during testing: the last session was changed from telephone to in-person; some components (e.g., sleep scheduling, mindfulness) were rearranged within or across sessions; sleep educator guidelines for sleep scheduling, light exposure, and walking were revised. After the fifth dyad, no additional issues were identified by the caregiver or the sleep educator. Four patients and three caregivers had improved sleep at the last session. CONCLUSIONS: The iterative refinement process was successful in finalizing the intervention program, with evidence of sleep improvements. Formal pilot testing of the program will provide further information on feasibility and effectiveness.IMPLICATIONS FOR REHABILITATIONOur dyadic behavioral sleep program can be tailored to various types of sleep problems among patients with Alzheimer's disease and their family caregivers, with the goal of improving daytime function by reducing sleep disturbances at night.Caregiver training and participation of both members of the dyad in sleep management may benefit the patients' sleep and other health outcomes, reduce caregiver stress and burden, and ultimately delay or prevent institutionalization of Alzheimer's disease patients.

Sleep apnea in women veterans: results of a national survey of VA health care users.

STUDY OBJECTIVES: The goals of this study were to estimate rates of undiagnosed, diagnosed, and treated sleep apnea in women veterans and to identify factors associated with diagnosis and treatment of sleep apnea in this population. METHODS: A large nationwide postal survey was sent to a random sample of 4,000 women veterans who had received health care at a Veterans Health Administration (VA) facility in the previous 6 months. A total of 1,498 surveys were completed. Survey items used for the current analyses included: demographics; sleep apnea risk, diagnostic status, and treatment; symptoms of other sleep disorders (eg, insomnia); mental health symptoms; and comorbidities. RESULTS: Among responders, 13% of women reported a prior sleep apnea diagnosis. Among women who reported a diagnosis of sleep apnea, 65% reported using positive airway pressure therapy. A sleep apnea diagnosis was associated with older age, higher BMI, non-Hispanic African American/Black racial/ethnic identity, being unemployed, other sleep disorder symptoms (eg, insomnia), depression and post-traumatic stress disorder symptoms, and multimorbidity. Among women without a sleep apnea diagnosis, 43% scored as "high risk" on the STOP (snoring, tiredness, observed apneas, blood pressure) questionnaire. High risk scores were associated with older age, higher BMI, African American/Black identity, other sleep disorder symptoms (eg, insomnia), mental health symptoms, and multimorbidity. Only BMI differed between women using vs not using positive airway pressure therapy. CONCLUSIONS: Women veterans with diagnosed sleep apnea were commonly treated with positive airway pressure therapy, which is standard first-line treatment; however, many undiagnosed women were at high risk. Efforts to increase screening, diagnosis, and treatment of sleep apnea in women with comorbid mental and physical health conditions are needed.

Efficacy of a patient decision aid for improving person-centered decision-making by older adults with obstructive sleep apnea.

STUDY OBJECTIVES: Person-centered obstructive sleep apnea (OSA) care is a collaborative approach that is respectful of an individual's health priorities. Informed decision-making is essential to person-centered care, especially as patients age. In a feasibility study, we evaluated the effects of a new decision aid (Decide2Rest) on OSA treatment decision-making in older adults. METHODS: Patients (aged ≥ 60 years) with newly diagnosed OSA were recruited from two health care systems and randomized either to Decide2Rest or to a control program. Postintervention outcomes included 1) Decisional Conflict Scale (0-100, where 0 = low and 100 = high conflict), which measures perceptions of uncertainty, whether decisions reflect what matters most to patients, and whether patients feel supported in decision-making; 2) Preparation for Decision-Making scale (0-100, where 0 = least and 100 most prepared); and 3) OSA knowledge (0-100, where 0 = poor and 100 = outstanding). Multivariable linear regression models examined relationships between Decide2Rest and outcomes (Decisional Conflict Scale, Preparation for Decision-Making, OSA knowledge). RESULTS: Seventy-three patients were randomized to Decide2Rest (n = 36; mean age, 69 years; 72% male) vs control (n = 37; mean age, 69 years; 70% male). Results from the regressions, controlling for study site, indicate that the Decide2Rest program resulted in less decisional conflict (20.5 vs 32.7 on the Decisional Conflict Scale; P = .014), more preparedness for decision-making (87.8 vs 66.2 on the Preparation for Decision-Making scale; P < .001), and greater OSA knowledge (75.1 vs 65.3 OSA knowledge score; P = .04) scores than in the control group. CONCLUSIONS: The Decide2Rest program promotes person-centered OSA decision-making for older patients with newly diagnosed OSA. Future studies are needed to optimize implementation of the program.

Randomized controlled trial of an integrated approach to treating insomnia and improving the use of positive airway pressure therapy in veterans with comorbid insomnia disorder and obstructive sleep apnea.

STUDY OBJECTIVES: Cognitive behavioral therapy for insomnia (CBTI) for comorbid insomnia and obstructive sleep apnea (OSA) has had mixed results. We integrated CBTI with a positive airway pressure (PAP) adherence program and tested effects on sleep and PAP use. METHODS: 125 veterans (mean age 63.2, 96% men, 39% non-Hispanic white, 26% black/African American, 18% Hispanic/Latino) with comorbid insomnia and newly-diagnosed OSA (apnea-hypopnea index ≥ 15) were randomized to 5-weekly sessions integrating CBTI with a PAP adherence program provided by a "sleep coach" (with behavioral sleep medicine supervision), or 5-weekly sleep education control sessions. Participants and assessment staff were blinded to group assignment. Outcomes (baseline, 3 and 6 months) included Pittsburgh Sleep Quality Index (PSQI), 7-day sleep diary (sleep onset latency [SOL-D], wake after sleep onset [WASO-D], sleep efficiency [SE-D]), 7-day actigraphy (SE-A), and objective PAP use (hours/night and nights ≥ 4 h). Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Functional Outcomes of Sleep Questionnaire-10 (FOSQ-10) were also collected. RESULTS: Compared to controls, intervention participants showed greater improvement (baseline to 3 and 6 months, respectively) in PSQI (-3.2 and -1.7), SOL-D (-16.2 and -15.5 minutes), SE-D (10.5% and 8.5%), SE-A (4.4% and 2.6%) and more 90-day PAP use (1.3 and 0.9 more hours/night, 17.4 and 11.3 more nights PAP ≥ 4 h). 90-day PAP use at 3 months was 3.2 and 1.9 h/night in intervention versus controls. Intervention participants also had greater improvements in ISI, ESS, and FOSQ-10 (all p < 0.05). CONCLUSIONS: An intervention integrating CBTI with a PAP adherence program delivered by a supervised sleep coach improved sleep and PAP use in adults with comorbid insomnia and OSA.

Racial disparities in positive airway pressure therapy adherence among veterans with obstructive sleep apnea.

STUDY OBJECTIVES: Black individuals are disproportionately affected by diabetes, cardiovascular disease, obesity, and OSA. Adherence to PAP therapy has been reported to be lower among black individuals. This study seeks to examine associations between black race and PAP adherence among veterans with OSA. METHODS: This was a retrospective study. Veterans newly diagnosed with OSA at a single Department of Veterans Affairs sleep center who were prescribed a modem-enabled PAP device between January 2015 and November 2017 were enrolled. PAP adherence was defined as ≥ 4 hours nightly usage for at least 70% of nights measured at 30 days from PAP setup. We examined the relationship between race and adherence, controlling for sex, marital status, age, socioeconomic status, residual apnea-hypopnea index), and mask leak. RESULTS: Of 3013 patients identified with OSA, 2571 (85%) were newly started on PAP therapy (95% male, aged 59 years ± 14 years, 45% married, 8% with neighborhood socioeconomic disadvantage). Twenty-five percent of participants were black, and 57% were white. PAP adherence at 30 days was 50% overall (42% among blacks, 53% among nonblacks). Black race was associated with reduced 30-day PAP adherence in unadjusted (P < .001) and adjusted logistic regression models (odds ratio = 0.64; 95% CI, 0.53 - 0.78; P < .001). CONCLUSIONS: Among veterans with OSA, black race was associated with reduced PAP adherence. These findings suggest health inequality among black individuals in the treatment of OSA.

Beyond the bladder: poor sleep in women with overactive bladder syndrome.

BACKGROUND: Nocturnal bladder symptoms and sleep disruption commonly coexist in middle-aged and older women. Although sleep disruption is often attributed to nocturnal bladder symptoms in women with overactive bladder syndrome, nonbladder factors also may influence sleep in this population. Many women with overactive bladder are eager to identify nonpharmacologic strategies for both bladder symptoms and sleep disruption, given the potential adverse effects of sedative and anticholinergic bladder medications in this population. OBJECTIVES: To provide greater insight into the complex relationship between nighttime overactive bladder symptoms and sleep disruption, and to evaluate the effects of a guided slow-paced respiration intervention on sleep outcomes in women with overactive bladder. STUDY DESIGN: We conducted an ancillary study within a randomized trial of slow-paced respiration in women with overactive bladder symptoms. Ambulatory community-dwelling women who reported ≥3 episodes/day of urgency-associated voiding or incontinence were randomized to use either a portable biofeedback device (RESPeRATE; Intercure, Ltd) to practice guided slow-paced respiration exercises daily for 12 weeks (N=79) or an identical-appearing device programmed to play nonrhythmic music without guiding breathing (N=82). At baseline and after 12 weeks, bladder symptoms were assessed by voiding diary, sleep duration, and disruption were assessed by sleep diary corroborated by wrist actigraphy, and poor sleep quality was determined by a Pittsburgh Sleep Quality Index global score >5. RESULTS: Of the 161 women randomized, 31% reported at least twice-nightly nocturia, 26% nocturnal incontinence, and 70% poor sleep quality at baseline. Of the 123 reporting any nighttime awakenings, 89% averaged 1 or more nighttime awakenings, and 83% attributed at least half of awakenings to using the bathroom. Self-reported wake time after sleep onset increased with increasing frequency of nocturnal bladder symptoms (P=.01 for linear trend). However, even among women without nocturia, average sleep quality was poor (Pittsburg Sleep Quality Index global score mean of 7.3; 95% confidence interval, 6.0-8.6). Over 12 weeks, women assigned to slow-paced respiration (N=79) experienced modest improvements in mean nocturnal voiding frequency (0.4 fewer voids/night), sleep quality (1.1 point score decrease), and sleep disruption (1.5% decreased wake time after sleep onset). However, similar improvements were detected in the music control group (N=81), without significant between-group differences. CONCLUSIONS: Many women with overactive bladder syndrome experience disrupted sleep, but not all nocturnal awakenings are attributable to bladder symptoms, and average sleep quality tends to be poor even in women without nocturia. Findings suggest that clinicians should not assume that poor sleep in women with overactive bladder syndrome is primarily caused by nocturnal bladder symptoms. Guided slow-paced respiration was associated with modest improvements in nocturia frequency and sleep quality in this trial, but the results do not support clinician recommendation to use this technique over other behavioral relaxation techniques for improving sleep.
